Black Sampson. (Eastern States of America.) N. O. Compositæ. Tincture of fresh root.
Clinical
Diphtheria / Putrid fevers
Characteristics
I mention this plant, which is a popular remedy in the Eastern States, because it has been used in place of Ech. ang. It has probably a very similar action, and the root causes the same pungent sensation on lips and tongue as the tincture of Ech. ang. It well deserves a proving. The black root has been taken as a "signature" of the remedy in cases of low fevers where a black tongue was observed.
